DAVID DAVIS, OF NEWARK, OHIO.

BRAN-PACKER.

SPECIFICATION forming part of Letters Patent No. 299,749, dated June 3,' 1884.l

Application filed September 17, 1883. (No model.)

the county of Licking and State of Ohio, have invented certain new and useful Improvements in Bran-Packers; and I do declare the following to be a full, clear, and exact description ofthe invention', such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figuresof reference marked thereon, which form a part of this speciiication.

Figure l of the drawings is a representation of a front elevation of my bran-packer. Fig. 2 is a rear elevation of the same. Fig. 3 is a vertical sectional View from front to rear, and Figs. 4, 5, and 6 are detail views.

This invention has relation to bran-packers designed to pack square packages 5 and it consists in the construction. and novel arrangement of devices, as will be hereinafter fully described, and particularly pointed out in the appended claims.

Referring by letter toy the accompanying drawings, a designates the iioor of the room in which the machine is built, and b is the ceiling of the room or floor of the upper room into which the studding of the frame of the machine is mortised in the usual manner practiced iu the construction of stationary machines.

c and c' are the two outer studs of the frame, which are connected near their upper ends by two cross-beams, d d', having a space, d2, betweenthem.

e e e e designate four grooved studs, which form guides for the piston-box f, which is rectangular in form and open at both' ends. The front of this piston-box f is provided with a rack-bar, j", which engages a pinion, f2, on a horizontal shaft, f3, having bearings in boxes f4 on the two front studs e e. This shaft f3 is provided with a ratchet, g, which engages a pawl, g2, pivoted to the right-hand stud e. The shaft fi is also provided with a handwheel, g', by which it is operated to raise and lower the piston-box in the vertical ways formed by the grooved post e e e e. The lower edge of the piston-box f is provided with a rubber gasket, y, for a purpose hereinafter explained. The rear wall of the piston-boxf is provided near its top with an aperture, h, having inclined top and bottom edges.

z' designates the piston, having rectangular top and-bottom plates or heads, z" i2, perforated centrally for the reception of the power-screw k, and connected by four vertical strips of a length equal to the height of the piston-box f, so that the piston will completely fill the latter when the piston is at its fullest extension downward. The power-screw Ic has its frictional bearing in the lower cross-beam, d, its friction-h-ead k resting on the upper face of said beam d, and its upper face bearing against the under face of the cross-beam d. Immediately beneath the cross-beam d the screw 7c is provided with a miter-gear, l, having the teeth on its lower face, said mitergear Z being rigm and m', a short distance below and one on,

each side of the mitergear Z, havetheir outer bearings in the studs c c and their inner bear ings in short pivoted bars a u, the rear ends of which are pivoted in vertical slots a2 in the rear studs c e, their free ends being permitted to work in vertical slots a3 in the front grooved studs e e, for a purpose hereinafter explained. The inner ends of the shafts m m are provided with miter-gears p p', which are arranged to be thrown in and out of gear with the mitergear Z by the following-described mechanism:

q q' designate two short arms pivoted in the slots a3 below the bars n n', and to the'inner endsv of these short arms q q are pivoted levers r q", which extend part way down the sides of the piston-box f. The tops of the sides of the piston-box j' are kerfed or recessed vertically at s s', and have recessed extensions s s3, in which are pivoted triggers tt', to engage the levers r r.

u designates an adjustable bran spout, through which the bran is delivered from the scale-hopper above the machine tothe pistonbox j', through the aperture 7L in the rear wall of the latter. The vadjustable portion uof the branspout u is provided with a rack, a2, in its rear face, which engages a spring-pawl, a3, secured to the inain spout, which is rigidly secured at its upper end to the ceilingv b. The lower end of the adjustable portion u is beveled from above down, and is provided at the lower edge of the bevel with a central beveled projection, n", which enters the aperture 71v and holds the spout .in place.

a designates the packing-box, which is of the same size in cross-section as the piston-bex f, and should be fifteen inches square to hold one hundred pounds of compressed bran. rlhe box e, piston-box f, and piston may be enlarged in proportion to form square packages of two hundred pounds of compressed bran, if desired, without departing from the charaeter of the invention. The packing-box U is provided with a door, fc', in front, and is provided also with half'staples w or slots in its top edges to receive the metal strap or wire af, by which the square-mouthed sack is heldin place preparatory to shoving the packing-box under the piston-box. rllhe sack is placed in the box and its mouth folded over the edges of the box, which is then placed under the piston-box, and the latter brought down upon it to hohl the sack iirmly in place. rlhe gasket before mentioned prevents injury to the sack while under the strain resulting from compressing the bran into it. The short shafts m fm1 are provided with pulleys .c e', connected by bands to a single shaft, the belt connecting with the pulley c beinggiven a quarter-turn, toimpart the necessary direction to the gearing on that side. The piston is run up in the piston-box by the gearing at the left-hand side of the machine, and the bran admitted to the piston box, through the branspout. The scalebeam of the scale-hopper should be nearthe piston -box to gage the number of pounds of bran delivered to the piston-box. The lever 1- at the right-hand side is pulled down, and a notch, l, in its inner face, is caught under the recessed projection 2, so that the inclined portion of the notch l will cover the recess in which the outer end of the trigger t new lies vertically. This will throw the gearwheel p into engagement with the miter-gear l, which causes the power-screw L to force the piston down into the piston-box and compress the bran or ground feed into the packing-box beneath. The inner arm of the trigger i, when set by the lever i', is projected horizontally into the piston-box, and when the upper head of the piston reaches the trigger it strikes this arm, projects the other arm from its recess, and throws off the levero' from its catch and lets the gear m. drop, t-hus stopping the downward motion of the piston in the piston-box. rlhe tri gger t is arranged with its inner arm, t2, bent up instead of down, as in trigger i, and a spring, t, is employed to hold it normally up. 'Vhen set to move the piston up in the piston-box, the outer arm is turned up in its recess, compressing the spring if* therein, and the lever i" is pushed up, andthe notch, which is the reverse of the notch in lever r, engages the top of the recessed projection and remains there until the bottoni of the piston strikes the trigger t and throws the lever 1" off the projection, when the lever i" and its gear will drop down. rlhe lever r will be next used, as before, to drive the piston down, and thus on throughout the operation of packing. After the requisite number of pounds have been compressed in the sack, the piston is run up, the pistoirbox raised, the packing-box removed, (it is not, however, necessary to remove the packing box,) the doors opened, and the sack taken out and closed ready for transportation.

The machine is quite simple, is not expensive, and does its work eii'eetually and rapidly. The machine may be built for transportation, and may be put up in any suitable place.

It should be noticed that the two front grooved studs c c are eut away near their lower ends to admit the packing-box to its place beneath the piston-bo.\.

Having thus fully described my invention, what lf claim as new, and desire to secure by Letters Patent, is l l. The combination, with the grooved studs c c c c, ofthe piston-boxj", working vertically therein and provided with a raclebar, and a shaft having its bearings in boxes secured to the two front studs, c c, and provided with a pinion, pawl and ratchet, and a hand-wheel, substantially as specified.

2. The combination, with the power-screw 7s, having the miter-gear l, of the imiter-gear p on the inner end of the shaft m, having its bearings in the post c and pivoted bar n, and

the pivoted arm q, carrying the lever i, the trigger tin recess in the upper edge of the piston-bony", and the piston on said screw le, substantially as specified.

3. The combination, with the piston-boxf, having the trigger 1, the pist-011 f/, and the power-serew 7.', having the miter-gear l at its upper end, of the horizontal shaft m, having its bearings in the. stud c', and the pivotcd bar a, and the pivoted arm g, carrying the lever o", substantially as specified.

et. In a bran-packer, the combination, with the pistoirboxf, having the aperture 7i in its rear wall near the top, of the adjustable branspout au', having the ratchet and spring-pawl, substantially as speciiied.

5. rlhe packing-box t, of the same size in cross-section as the piston-box j', provided with a door, and having half-staples or top slots, in combination with the grooved studs c c c c and the piston-boxj', having a rubber gasket on its lower edge, substantially as specified.

In testimony whereof I aflix my signaturein presence of two witnesses.

DAVID J. DAVIS.
